Abstract
The starting process of the flow in a wedge-like expansion nozzle of a shock tunnel is simulated by an unsplit 2-D GRP scheme on an unstruct ured grid. The scheme is briefly outlined and results are presented an d discussed in comparison to the experimental (shadowgraph) findings o btained by Amann. The simulated pattern of reflected and transmitted s hock waves in the nozzle inlet region and inside the nozzle is found t o agree well with the experimental data.
